My principal interest is in the politics of deeply divided societies, most particularly the cases of South Africa and Northern Ireland (see book on connections between the two below). Although I have done some work on each as individual cases, I have an especial interest in comparison of deeply divided societies and any role that comparison has played in their politics. In the past I have done a considerable amount of research on political violence both in deeply divided societies and more widely. This led me to carry out a study of terrorism, a subject that also fits into my interest in the international dimensions of internal conflicts, crossing the boundaries between International Relations and Comparative Politics.
I chaired the Advisory Board for the latest Northern Ireland Peace Monitoring Report (No.5, October 2018) of the Community Relations Council. The report can be found here: https://www.community-relations.org.uk/sites/crc/files/media-files/NIPMR%205.pdf
I also contributed to History Extra debate on terrorism (May 2017), see: https://www.historyextra.com/period/modern/the-big-question-has-terrorism-ever-achieved-its-aims/
